ABSTRACT:
An overall roof arrangement is disclosed herein and includes a roof structure comprised of a roof deck, roof insulation disposed over the deck and a built-up roof disposed over the insulation. This overall arrangement also includes a one-way vent through which moisture within the roof structure and subsequently converted to vapor passes to the ambient surroundings. However, this vent prevents moisture vapor in the ambient surroundings from being drawn back into the roof structure through the vent.
